EPSON Stylus C67/C68/D68 Revision A
OPERATING PRINCIPLES Overview 23
2.1 Overview
This section describes the operating principles of the printer mechanism and electrical
circuit boards.
2.2 Printer Mechanism
Printer mechanism of Stylus C67/C68/D68 consists of printhead, carriage mechanism,
paper loading mechanism, paper feeding mechanism, and ink system.
As in the case of conventional models, Stylus C67/C68/D68 has two DC motors; one is
for paper loading/feeding mechanism, and the other is for carriage mechanism.
Papers are fed from the backside and ejected from the front side of the printer.
Paper feeding mechanism, which is also similar to conventional models, feeds papers
using the LD roller and the retard roller.
